GM says that 150ºF is the desired minimum operating temp for the 6L80.In the cooler times of the year, see if you can fabricate some type of cardboard
or plastic sheet material that could cover the TruCool itself. That should help get your
temps over 100. I "think" temps of 110+ would be preferable
Depends on how long of drives you are doing.
